Electromagnetic Suspension (EMS) trains utilize electromagnets within the train to attract the train to the metal track. Because this type of Maglev train relies upon magnetic attraction, it has to be closely monitored electronically.
Maglev trains use electromagnetic force to levitate several inches over the track or guideway. By eliminating a key source of friction—that of the wheels on the rails—such trains can reach higher speeds than conventional trains, have longer lasting parts, and are very quiet and smooth to ride.
Maglev trains operate on the principle of electromagnetic propulsion, which involves the use of powerful magnets to lift and propel the train along the tracks. These trains are equipped with powerful electromagnets on the underside of the train that repel against fixed magnets on the trackway.
An electromagnetic train, also known as a maglev train, works by using magnetic levitation to lift and propel the train along a guideway without the need for wheels.

In the 21st century there are a few countries using powerful electromagnets to develop high-speed trains, called maglev trains. These trains float over guideways using the basic principles of magnets to replace the old steel wheel and track trains.
In electromagnetic suspension (EMS) systems, the train levitates by attraction to a ferromagnetic (usually steel) rail while electromagnets, attached to the train, are oriented toward the rail from below.
There are two main types of maglev train that use magnetism in different ways. Electromagnetic suspension (EMS) uses C-shaped arms that wrap underneath the track. Electromagnets on the underside pull the train up by attracting the arms to the bottom of the track.
